I tried that but this also fails, slightly differently though.
One point seems to be that -isValid does not seem to be correct. When I
check this in BibDesk, it also returns NO, but we know it works. BTW, the
port in your code is not nil.
When I try my proposal, the it seems to work, including an NSConnection.
However when I try to send a DO message I get a log (not an exception)
saying
*** NSDistantObject initWithCoder: 0x2 not given away for conn 0x113140
